纤维素织物在土壤中的生物处理
Biological Treatment of Cellulose Fabrics in Soil
摘要
Abstract
The biodegradability of cellulose fabrics such as cotton,flax and viscose was studied by the soil burial method.The changes of morphological appearance and microstructure of fabrics were studied.The results show:the longer the degradation time was,or the shallower the burying depth was,and then the more serious the biodegradability of cellulose was; in the better conditions of degradation,the degradation rate of the flax was the highest,and the degree of damages to the appearance was the most serious.The infrared spectrum showed that there was little change in the position of the main characteristic peak of the three fibers before and after degradation,which indicated that the structure of the cellulose molecule had no significantly change.The study on X-ray diffraction showed a new diffraction peak for the three fabrics formed at the position of 2θ =26.6°.the intensity of the diffraction peak gradually increased with the degradation time,but there was no significant change with the rise in the burying depth.After degradation,the variation tendency of the degree of crystallinity of the three fibers with the degradation time and the burying depth was relatively complicated.关键词
